I'm hoping someone has luck with this as I had none.
I own Pearl and would be Platinum if I could transfer my save file to it. I tried transferring my Pearl save file to a JPN Platinum rom but nothing went over except for I think things like money, trainer id, etc. My name didn't go (it was in English, probably wow) and I had no save data, pokemon, etc. I guess I'll try later with the English version. I seriously do not feel like playing this all over. It would be nice to just transfer save files between games.
